In supported launchers on devices running Android 8. Users can long-press on an app icon to see the notifications for that app. Users can then dismiss or act on notifications from that menu, similar to the notification drawer.
Figure 5. Notification badges and the long-press menu. To learn more about how badges work, read Notification badges. If the user has a paired Wear OS device, all your notifications appear there automatically, including expandable detail and action buttons.
You can also enhance the experience by customizing some appearances for the notification on wearables and provide different actions, including suggested replies and voice input replies.
For more information, see how to add wearable-specific features to your notification. Figure 6. Notifications automatically appear on a paired Wear OS device.
The design of a notification is determined by system templates—your app simply defines the contents for each portion of the template.
Some details of the notification appear only in the expanded view. Figure 7. A notification with basic details. For more information about how to create a notification with these features and more, read Create a Notification.
Although it's not required, every notification should open an appropriate app activity when tapped. In addition to this default notification action, you can add action buttons that complete an app-related task from the notification often without opening an activity , as shown in figure 9.
Figure 9. A notification with action buttons. Starting in Android 7. Starting in Android 10 API level 29 , the platform can automatically generate action buttons with suggested intent-based actions.
Adding action buttons is explained further in Create a Notification. By default, the notification's text content is truncated to fit on one line. If you want your notification to be longer, you can enable a larger text area that's expandable by applying an additional template, as shown in figure 8.
Figure 8. An expandable notification for large text. You can also create an expandable notification with an image, in inbox style, a chat conversation, or media playback controls.
For more information, read Create an Expandable Notification. And although we recommend you always use these templates to ensure proper design compatibility on all devices, if necessary, you can also create a custom notification layout.
To avoid bombarding your users with multiple or redundant notifications when you have additional updates, you should consider updating an existing notification rather than issuing a new one, or consider using the inbox-style notification to show conversation updates.
However, if it's necessary to deliver multiple notifications, you should consider grouping those separate notifications into a group available on Android 7.
A notification group allows you to collapse multiple notifications into just one post in the notification drawer, with a summary.
The user can then expand the notification to reveal the details for each individual notification. The user can progressively expand the notification group and each notification within it for more details.
Figure A collapsed and expanded notification group. To learn how to add notifications to a group, see Create a Group of Notifications.
Starting in Android 8. By categorizing notifications into channels, users can disable specific notification channels for your app instead of disabling all your notifications , and users can control the visual and auditory options for each channel—all from the Android system settings figure Users can also long-press a notification to change behaviors for the associated channel.
On devices running Android 7. Notification settings for Clock app and one of its channels. One app can have multiple notification channels—a separate channel for each type of notification the app issues.
An app can also create notification channels in response to choices made by users of your app. For example, you may set up separate notification channels for each conversation group created by a user in a messaging app.
The channel is also where you specify the importance level for your notifications on Android 8. So all notifications posted to the same notification channel have the same behavior.
For more information, see Create and Manage Notification Channels. Android uses the importance of a notification to determine how much the notification should interrupt the user visually and audibly.
The higher the importance of a notification, the more interruptive the notification will be. On Android 8.
Users can change the importance of a notification channel in the system settings figure On Android 7. Users can change the importance of each channel on Android 8.
All notifications, regardless of importance, appear in non-interruptive system UI locations, such as in the notification drawer and as a badge on the launcher icon though you can modify the appearance of the notification badge.
For more information, see how to set the importance. Starting in Android 5. Notifications still appear in the system UI as normal, unless the user specifies otherwise.
Users can can allow notifications through based on system-wide categories left and based on who sent a message or who is calling right. For example, a payment app might have channels for notifications related to withdrawals and deposits.
The user can then choose to allow either withdrawal notifications, deposit notifications, or both when in priority mode. To properly configure your notifications for these user settings, you must set a system-wide category and channel.
A notification is required when your app is running a "foreground service"—a Service running in the background that's long living and noticeable to the user, such as a media player.
This notification cannot be dismissed like other notifications. To remove the notification, the service must be either stopped or removed from the "foreground" state.
For more information read Running a service in the foreground. And if you are building a media player, also read Using MediaStyle notifications with a foreground service.
Beginning with Android 8. If your app posts multiple notifications in one second, they all appear as expected, but only the first notification per second makes a sound.
However, Android also applies a rate limit when updating a notification. If you post updates to a single notification too frequently many in less than one second , the system might drop some updates.
Since Android 1. NotificationCompat is updated as the platform evolves to include the latest methods. It is important to note that the availability of a method in NotificationCompat does not guarantee that the corresponding feature will be provided on older devices.
In some cases calling a newly-introduced API results in a no-op on older devices. For example, NotificationCompat. Content and code samples on this page are subject to the licenses described in the Content License.

It is your job to take this subscription object and store it somewhere on your system. For instance, you might store it in a database attached to a user object.
In our examples, we will log results to the console. First, we need to check if we already have a subscription object and update the UI accordingly.
We should perform this check whenever the user accesses our app because subscription objects may change during their lifetime.
We need to make sure that it is synchronized with our server. If there is no subscription object we can update our UI to ask the user if they would like receive notifications.
It's best practice to call the subscribeUser function in response to a user action signalling they would like to subscribe to push messages from our app.
In the above example we call the subscribe method on the pushManager and log the subscription object to the console. Notice we are passing a flag named userVisibleOnly to the subscribe method.
By setting this to true , the browser ensures that every incoming message has a matching and visible notification.
If the user doesn't accept the permission request or there's another error, the promise rejects. We add a catch clause to handle this, and then check the permission property on the notification global object to understand why we can't display notifications.
Let's look at how to send a push message to the browser using the Web Push Protocol. The Web Push protocol is the formal standard for sending push messages destined for the browser.
It describes the structure and flow of how to create your push message, encrypt it, and send it to a Push messaging platform.
The protocol abstracts the details of which messaging platform and browser the user has. The Web Push protocol is complex, but we don't need to understand all of the details.
The browser automatically takes care of subscribing the user with the push service. Our job, as developers, is to take the subscription token, extract the URL, and send our message there.
FCM recently adopted the Web Push protocol. Here's how:. For example, the manifest could look like this:. To get FCM to push a notification without a payload to your web client, the request must include the following:.
A production site or app normally sets up a service to interact with FCM from your server. Check out the Web Fundamentals documentation for more information.
We can test push messaging in our app using cURL. We can send an empty message, called a "tickle", to the push service, then the push service sends a message to the browser.
If the notification displays, then we have done everything correctly and our app is ready to push messages from the server.
You can send a message to Firefox using the same cURL command, but without the Authorization header:.
It's relatively easy to get a push message to the user. However, so far the notifications we have sent have been empty.
Chrome and Firefox support the ability to deliver data to your service worker using the push message. Let's first look at what changes are needed in the service worker to pull the data out of the push message.
When we receive a push notification with a payload, the data is available directly on the event object. In order to send data, the push message must be encrypted with the key information from the subscription object.
As with anything related to encryption, it's usually easier to use an actively maintained library than to write your own code. We are using Mozilla's web-push library for Node.
This handles both encryption and the web push protocol, so that sending a push message from a Node. The first argument is the the subscription object.
The second argument is the payload. The third is an options object that contains various options to configure the message.
See the documentation for details. While we recommend using a library, this is a new feature and there are many popular languages that don't yet have any libraries.
Here is a list of some available web-push libraries for various languages. If you do need to implement encryption manually, use Peter Beverloo's encryption verifier.
We now have all the client side components in place, so let's create a simple server-side script using Node.
This example passes the subscription object, payload, and server key into the sendNotification method. It also passes in a time-to-live, which is the value in seconds that describes how long a push message is retained by the push service by default, four weeks.
The Web Push Protocol has been designed to respect the user's privacy by keeping users anonymous and not requiring strong authentication between your app and the push service.
This presents some challenges:. At a minimum, this provides a stable identity for the application server, though this could also include contact information, such as an email address.
You can see how to do this in the web-push node library :. You'll know if it has worked by examining the endpoint in the resulting subscription object; if the origin is fcm.
Let's look at these new headers in detail. A JWT is a way of sharing a JSON object with a second party in such a way that the sending party can sign it and the receiving party can verify the signature is from the expected sender.
The structure of a JWT is three encrypted strings, joined with a single dot between them. The JWT Header contains the algorithm name used for signing and the type of token.
The Signature is the result of joining the encoded header and payload with a dot then encrypting the result using the VAPID private key you created earlier.
The result itself should be appended to the header with a dot. There are a number of libraries that will take the header and payload JSON objects and generate this signature for you.
The signed JWT is used as the Authorization header, with "WebPush" prepended to it, and looks something like the following:.
There are a few things to point out here. Also notice the dots separating the JWT header, payload, and signature.
When you are sending a notification with encrypted data, you will already be using the Crypto-Key header, so to add the application server key, you just need to add a comma before adding the above content, resulting in:.
It contains the subject your email address and the generated Public and Private keys. The library takes care of encrypting the message, generating and signing the JWT, and adding the Authorization and Crypto-Key headers to the request.
See the web-push documentation for more information on how to use the library. While it's relatively simple to get notifications up and running, making an experience that users really value is trickier.
There are also many edge cases to consider when building an experience that works well. Notifications should be timely, precise, and relevant.
By following these three rules, you'll keep your users happier and increase their return visits. Timely — The notification should display at the right time.
Use notifications primarily for time-sensitive events, especially if these synchronous events involve other people.
For instance, an incoming chat is a real-time and synchronous form of communication another user is actively waiting on your response.
Calendar events are another good example of when to use a notification to grab the user's attention, because the event is imminent and often involves other people.
Precise — Offer enough information so that the user can make a decision without clicking through to the web page.
Because users often give notifications only a quick glance, you can make their lives easier with a well-chosen title, description, and icon.
If possible, make the icon match the context of the notification so users can identify it without reading. Relevant — Make notifications relevant to the user's needs.
If the user receives too many unimportant notifications, they might turn them all off. So keep it personal. If it's a chat notification, tell them who it's from.
Avoid notifications that are not directed specifically at the user, or information that is not truly time-sensitive.
For instance, the asynchronous and undirected updates flowing through a social network generally do not warrant a real-time interruption.
Don't create a notification if the relevant new information is currently on screen. Instead, use the UI of the application itself to notify the user of new information directly in context.
For instance, a chat application should not create system notifications while the user is actively chatting with another user. To show notifications we need to prompt the user to give permission.
But when is the best time to do that? Geolocation offers a good example of where we can look at people's experience with its prompts.
Although geolocation is a great API, many sites immediately prompt the user for their location the instant that the page loads.
This is a poor time to ask. The user has no context for how to make an informed decision about allowing access to this powerful piece of data, and users frequently deny this request.
Acceptance rates for this API can be as low as six percent. However, when the user is presented with the prompt after an action such as clicking on a locator icon, the acceptance rate skyrockets.
The same applies to the push notifications. If you ask the user for permission to send push notifications when they first land on your site, they might dismiss it.
Once they have denied permission, they can't be asked again. Case studies show that when a user has context when the prompt is shown, they are more likely to grant permission.
Another pattern that works well is to offer a very subtle promotion area on the screen that asks the user if they would like to enable notifications.
Users can turn sounds on or off, and pick the style that iOS uses to show a notification. Android uses a standard banner approach that users cannot change at an OS level.
All mobile operating systems ask users for their permission to share location information. Publishers can deliver more relevant messages by using location data combined with behavioral data.
Examples include:. Push notifications are a direct path of communication with users. App publishers should treat the ability to communication with users via push notifications as a privilege, not a right.
Some users will uninstall the app altogether. Messaging strategies and tactics need to be measured and tested. Other strategies include:.
